goat grass and non-native invasive weeds, such as yellow sweet clover, bindweed, and kochia in GuSG habitat reclamation. • Reclaim GuSG habitats with native grasses including bunchgrasses and forbs attractive to GuSG and other wildlife appropriate to the site. Additional Considerations Colorado law requires that invasive noxious weeds be managed and controlled through standard weed maintenance and controls (see C.R.S. Title 35, Article 5.5). Uncontrolled infestations of noxious weeds permanently alter native plant communities upon which wildlife depends. Early detection and initial control of weed infestations is critical to a successful weed control plan (Zamora and Thill 1999). We recommend developing a weed management plan that includes: educating construction crews and project staff on the identification of Colorado's noxious weeds, and incorporating a reporting and maintenance system for early detection and control of weeds; and a cleaning program for all work vehicles, construction and drilling equipment to remove seeds and/or pieces of noxious weeds. (This procedure helps minimize the introduction and spread of noxious weeds, as well as the need for costly weed control, later.) Summary We appreciate the opportunity to comment on this project during the planning phase. If you have additional questions or wish to discuss our recommendations, please contact local District Wildlife Manager Tyler Kersey at (970)422-2173. We look forward to working with you to benefit wildlife.
